Answer:
[tex](3+xz)(-3+xz)[/tex]
[tex](y^2-xy)(y^2+xy)[/tex]
Step-by-step explanation:
The Difference of Squares
Any difference of two squared monomial results in a factored form like shown below:
[tex]a^2-b^2=(a-b)(a+b)[/tex]
Similarly:
[tex](a-b)(a+b)=a^2-b^2[/tex]
For a product of binomials to be a difference of squares, they must be in the described form.
------------------------
(x-y)(y-x) can be rewritten as:
-(x-y)(x-y)
Since both binomials are identicals, the product will not result in a difference of squares.
-----------------------
(6-y)(6-Y)
Since both binomials are identicals, the product will not result in a difference of squares.
-----------------------
(3+xz)(-3+xz) can be rewritten as:
(xz+3)(xz-3). This product is a sum multiplied by a difference of the very same terms, thus the result is a difference of squares:
[tex](3+xz)(-3+xz)=(xz)^2-9[/tex]
-----------------------
[tex](y^2-xy)(y^2+xy)[/tex]. This product is a sum multiplied by a difference of the very same terms, thus the result is a difference of squares:
[tex](y^2-xy)(y^2+xy)=y^4-(xy)^2[/tex]
-----------------------
Summarizing:
(3+xz)(-3+xz)
[tex](y^2-xy)(y^2+xy)[/tex]

Answer:
20
Step-by-step explanation:
We know that a triangle's angles must add up to 180 which means that
100+40+2x=180
solve for x
140+2x=180
2x=40
x=20
The angle of elevation from a boat to the top of a lighthouse is 50°.
If the boat is 150 feet from the base of the lighthouse, how tall is the lighthouse?
Round answer to the nearest foot.
9514 1404 393
Answer:
179 ft
Step-by-step explanation:
The applicable trig relation is ...
Tan = Opposite/Adjacent.
The height of the lighthouse is the opposite side of the right triangle. The adjacent side to the angle of elevation from the boat is the distance to the lighthouse base. Then ...
tan(50°) = height/(150 ft)
height = (150 ft)(tan(50°)) ≈ 178.76 ft
The height of the lighthouse is about 179 feet.

Answer:
CASH = 7284
Step-by-step explanation:
MATHEMATICS = 12345123678
CASH = ?
Find what number the letters represent:
M = 1
A = 2
T = 3
H = 4
E = 5
I = 6
C = 7
S = 8
Then, replace the numbers in the word CASH:
C = 7
A = 2
S = 8
H = 4
Therefore, the number is 7284.

(9b + 5) + (3b – 6)
change 4x - 5y = 10 into slope intercept form and graph
Answer:
Slope intercept form: y = 4/5x - 2
Step-by-step explanation:
(subtract 4x from both sides) -5y = -4x + 10
(divide everything by -5) y = 4/5x - 2
To graph, place a point at (0,-2), and then travel up 4 and over right 5 (or down 4 and to the left 5) to place the next point, then draw a line through the points

Pls help! I WILL MARK BRAINLIEST IF YOU ARE CORRECT
everyone if you can help that would be great
Answer:
the answer is 2.87
Step-by-step explanation:
use the pythagorean theorem
2^2+b^2=4^2
that goes to b= 3.5
for the triangle with x you also need to use the pythagorean theorem
[tex]2^{2}[/tex]+[tex]x^{2}[/tex]=[tex]3.5^{2}[/tex]
4+[tex]x^{2}[/tex]=12.25
subtract 4 on both sides
[tex]x^{2}[/tex]=8.25
[tex]\sqrt{x}[/tex]=[tex]\sqrt{8.25}[/tex]
x=2.87

Pix diameter = Circumference
A group of students stood in a circle to play a game. The circle had a diameter of 22 meters.
Which measurement is closest to the circumference of the circle in meters?
A 34.54 m
B 1,519.76 m
C 379.94 m
D 69.08 m
Answer:
69.08m
Step-by-step explanation:
Circumference of a circle = πd where
d is the diameter of the circle
Given
diameter = 22metres
circumference of the circle = 3.14(22)
circumference of the circle = 69.08m
Hence the circumference of the circle is 69.08m

the measure of the hypotenuse is? (side c)
The answer is 25
Sooooo to find the hypotenuse you gotta use this formula: a^2+b^2=c^2.
Please help I’m failing math and I might get held back
Answer:
[tex]tan 56 = \frac{26}{x}[/tex]
Step-by-step explanation:
[tex]tangent = \frac{opposite}{adjacent}[/tex]
Side z is the hypotenuse, since it is opposite the right angle.
Side x is the adjacent, since it is next to the angle you are solving for.
The side measuring 26 is the opposite, since it is opposite the angle you are solving for.

Kahleela starts the engine on her small private airplane. The engine drives a propeller with a radius of 8.5 feet and its centerline 11.5 feet above the ground. At idle, the propeller rotates at a constant speed of approximately 800 revolutions per minute. The height of one propeller tip as a function of time is given by h = 11.5 + 8.5 sin(800t), where h is the height in feet and t is the time in minutes. Find h when t = 5.5 minutes.
Answer:
a=21.1
Step-by-step explanation:
You can use the given (incorrect) equation and fill in the value of t to find h:
h = 12.5 +9sin(750(3.5)) = 3.68 . . . . feet
__
Or, you can use the correct equation, or just your knowledge of revolutions:
h = 12.5 +9sin(750(2π·3.5)) = 12.5 . . . . feet
in 3.5 minutes at 750 revolutions per minute, the propeller makes 2625 full revolutions, so is back where it started — at 12.5 feet above the ground.

Answer: We all hate it when we are stuck! The slope is -1/2.
Step-by-step explanation: To find the slope, figure out the change of x divided by the change of y. The change of y is -1, and the change of x is 2. Therefore, the slope of the line is -1/2.

Consider the sequence of steps to solve the equation: 2(x – 4) + 6x = 9x – 10
Given = 2(x - 4) + 6x = 9x - 10
Step 1 = 2x - 8 + 6x = 9x - 10
Step 2 = 2x + 6x - 8 = 9x - 10
Step 3 = 8x - 8 = 9x - 10
Step 4 = 8x – 8x - 8 = 9x - 8x - 10
Step 5 = 0 - 8 = x - 10
Step 6 = -8 = x - 10
Step 7 = -8 + 10 = x - 10 + 10
Step 8 = 2 = x + 0
Step 9 = 2 = x
